The OH 5 skull from Olduvai Gorge in Tanzania is widely recognized as the most famous fossil found to date. Mary Leakey discovered this remarkable specimen in 1959, and L. Leakey initially classified it as Zinjanthropus boisei in a Nature article later that year. However, the scientific community has since accepted Australopithecus as its genus name. This iconic fossil is also referred to by many scientists using the genus name Paranthropus. The discovery of OH 5 marked a significant turning point for paleoanthropology, shifting the field toward a more modern and multidisciplinary approach, and focusing the attention of paleoanthropologists on East Africa. One of the unique characteristics of A. boisei is its massive skull, featuring a wide, concave face, enormous flat molars that are approximately four times larger than those found in modern humans (Homo sapiens), and cranial adaptations designed for powerful chewing, earning it the nickname Nutcracker Man. Noticeable features include the sagittal crest and an extremely large area on the zygomatic arch for muscle attachment. The thick jaw of A. boisei allowed the species to excel at chewing, while its cranial capacity measures 530 cubic centimeters in this particular individual.
